Claim
17-by-22-inch (559 by 432 mm)
Correction
The metric conversion is reversed. A 17-by-22-inch poster is about 432 by 559 mm, not 559 by 432 mm.
Full reasoning
The Smithsonian’s object record for "We Can Do It!" gives the poster’s measurements as 22 in x 17 in; 55.88 cm x 43.18 cm. That corresponds to roughly 559 mm x 432 mm in that same 22-by-17 order. Separately, NIST states that 1 inch is exactly 25.4 mm. So:
- 17 in × 25.4 = 431.8 mm
- 22 in × 25.4 = 558.8 mm
That means a 17-by-22-inch poster should be written as approximately 432 by 559 mm if the metric dimensions are kept in the same order. The article’s parenthetical "(559 by 432 mm)" swaps the dimensions.

The value for the inch, derived from the value of the Yard effective July 1, 1959, is exactly equivalent to 25.4 mm.
